None of the Above: Who Are They? - Part One of a three-part series on the fast-growing number of Americans - now twenty percent of US adults - who have no affiliation with any religious organization. Host Bob Abernethy reports the results of a joint Pew Forum/Religion& Ethics NewsWeekly survey on the characteristics of the unaffiliated, especially the one-third of young people 18 to 29 who describe themselves as atheists, agnostics or "nothing in particular." Why is this group growing so fast, and what are the implications of this growth for politics and religion? Vatican Nuns Controversy - Fifty years ago Pope John XXIII convened a series of meetings in Rome known as the Second Vatican Council, which produced significant changes in Catholic life. But the legacy of Vatican II is still debated. Kim Lawton reports on how that debate has played a role in the current crisis between the Vatican and many US nuns. Last April, the Vatican accused the umbrella group that represents the majority of American nuns of "doctrinal confusion." But many of these sisters say they are just following the spirit of Vatican II.
